To a. whom it may concern:

Be it known that I, ALEXANDER J. SToE- sea, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Molding Walls, (520., of which the following is a full, clear, and exact specification.

. My invention relates to machines for molding concrete walls one section or block at a time directly upon the wall for-various purposes-such as buildings, silos, &c.; and the invention has for its primary object to provide a machine of this character which will be easy to operate and will be of comparatively simple and inexpensive construction.

With the described ends in view the invention consists in the feature of novelty in the construction, combmatlon, and arrangement of parts shown in the accompanying draw ings and hereinafter fully described, with ref erence thereto, and particularly pointed out in the claims.

In the said drawings, Figure 1 is a plan view of my improved machine ada ted for Fig. 2 is a vertica central section taken longitudinally of theoperatingscrew. Fig. 3 is anenlarged detail cross-section on the line 3 3, Fig. 1. Fig. 4 is a view similar to Fig. 1, illustrating a modification whereby the angle of the corner to be molded may be varied. Fig. 5 is a cross-section thereof on the line 5 5, Fig. '4. Fig. 6 is a cross-section on the line 6 6, Fig. 4. Fig. 7 is a side elevation thereof. Fig. 8 is an enlarged detail sectional view on the line 8 S, Fig. 9. Fi 9 is an enlarged detail crosssection ont e lines 9 9, Fig. 8, and 6 6, Fig.4. Fig. 8 is a section on line a a, Fig. 4. Fig. 10 is a detail plan section on the line 10 10, Fig. 7. Fig. 11 isa plan view of the machine, showing a form suitable for molding silos or other curved walls. Fig. 12 is a front elevation' thereof with the lower portion broken away. Fig; 13 is a side elevation thereof. Fig. 14 is a rear end elevation. Fig. 15 is' an enlarged detail section on the line 15 15, Figs. 11 and 16; and Fig. 16 is a cross-section on l the line 16 16, Fig. 15.

In Figs. 1 to 3 of the drawings, which show a form of the machine for molding corners, the lates which constitute the walls of the rriol are bent at an angle to each other, and this angle in this form is a fixture; but the walls themselves are relatively movable or adjustable for the twofold purpose of vary- 1 ing the thickness of the wall to be molded and of relieving the pressure of the mold on the newly-formed'wall, so that the machine may be lifted off. These walls of the mold are shown at 1 2 3 4 and so arranged as to constitute one or more mold-cavities 5 6, with an air-space 7 between them, two pairs of the mold-walls being thus employed when it is desired to mold what is known as hol low walls or an inner and an outer wall with an air-space between them, the width of which is determined by the distance between the two walls 2 3. The plates or walls 1 2 3 4 are bent at their mid-lengths along vertical lines to form angles or corners, and these corners may of course be any desired angle prevlously determined upon and which angle will be maintained throughout any relative adjustments of'said walls.

At the bends of the walls 1 2 3 4 they are rovided with brackets 8 9 1O 11, and the rackets 9 and 11, which belong to the walls 24, the same being the outer mold-wall of the mold-cavity 6 and the inner mold-wall of the mold-cavity 5 and which are the walls that move to release the machine from the molded sections, are bifurcated, as shown at 12 13, respectivchy, and in the bifurcations are located rotatable nuts 14 15, respectively, through which passes an operating-screw 16. The brackets S and 10, however, are formed with plain collars 17- 18, through which the screw loosely passes, thus serving to support and guide the mold-walls 1 3, and consemay be done by a handle 19, the walls 2 and 4 would be moved back and forth, thus increasing or decreasing the width of the moldcavities 5 6 for allowing themachine to be lifted on the newly-molded section and to be readjusted for molding another section of the same thickness.

The screw 16 is held against l iu1gitudinal movement by any suitable means, such as a collar 20, fixed thereto on one side of a bracket 21, in which the end of the screw is journaled, and handle 19, fixed thereto on the other side of the bracket 21, the bracket itself being attached to the wall 1. The walls 1 and 3 are held against movement when the screw moves the walls 2 4 by being suitably attached to cross-bars 22 23, extending across their upper edges near their ends, as shown in Fig. 1. This attachment is eifected through. the agency of end brackets 24, the same in construction and secured re quently when the screw 16 is rotated, which the outer sides of the plates or walls 1 and 3 and having collars 25, through which the rods 22 23 pass and on which rods the collars are ri idly secured at any desired adjustment y any suitable means, such as setscrews 26, so that while the walls 1 3 are rig idly held in place during the opei ation of the p .machine they are susceptible of adjustment relative to their companion walls when the set-screws 26 are loosened, thus providing nected together at one end of the machine by a cross-brace 29, which, if desired, may be formed with a collar for the free passage of one end of the screw 16, and depending from this cross-brace 29 is a brace 31, supporting the wall '4 at a low point for resisting outward movement.

In the ordinary operation of the machine after the walls of the mold-cavities have once been adjusted for molding walls of the de 0 sired thickness the walls 2 and 4 only are moved back and forth by thescrew 16 when it is desired to remove the machine from the newly-molded section and to set it again in place for molding another section; but

5 should it be desired to mold sections of a I the wall 3 could be moved forward or back 2 and 4 would be moved to increase the disdi'lferent thickness the set-screw 26, belonging to the wall 3, would be loosened, so that for either increasing or decreasing the space Tnen by turning the screw 16 the walls tance between them and their com anion walls, the wall 1 remaining fixed witrelation to the screw 16 and the bars 22 23.

5 Should it be desired to change the relative positions of the walls 2 and 4, the distance etween which remainsthe same during the operation of the screw 16, the desired end may be accomplished by turning one or both 50 of the nuts 14 15 on the screw 16, it being ob served in Fig. 3 that these nuts are formed with notches 32, in which engages a locking.

dog or pawl 33 for holding the nuts against rotation at other times. v

In the form shown in Figs. 4 to 10, inclusive, the an le of the corner to be molded is made varialile by hinging one-half of each of the mold-walls. These Walls, which correspond to the walls 1 2 3 4 of Fig. 1, are composed of two sections 34 34",35 35, '36 36 and 37 37, the sections 34 to 37 being rigid sections and the others hinged sections .pivotally connected to tlieformer sections by suitable hinges 38, arranged on vertical axes, and the rounded portion of the hinge erence to Fig. 1.

companion wall-sections.

in eaeh instance being located atthe outer side of .the mold-walls, so as to not indent the molded wall. The mold-wall 34 34 and the mold-wall 3636 are fixed with relation to their companion walls during the ordinary. operation anion-walls 35 35 and 37 37 move bodily without changing their angle during the ordinary operation of the machinethat is, in releasing the machine from the molded well, just as in the form described with ref- To that endthe wall-sec? of the machine, and their com-' tion 34 is rigidly secured at one end to a bar 39, extending across the .upper edgesof all of the walls near one end of each, the wallsection 34 being provided with a bracket 40, having a collar 41, throu h which the rod 39 passes and to which rod the collar is secured by set-screw 42 or other suitable means. The wall-section 36 is provided with a similar bracket 43, having a collar.44, through.

which. passes the rod 39 and to which rod the collar is secured by set-screw 45, so that while the wall-sections 34 36 are capable of being adjusted longitudinally of the rod 39 they may be locked rigidly in position during the operation of the machine. I

Arranged below and parallel with the rod 39 is a screw .46, which passes loosely through the brackets 40 43, so as not to interfere with the movement of the brackets 40 43 when the set-screws 42 45 are loosened; but this screw has screw-threaded connection with the wall-sections 35 37' by any suitable means-such, for example, as nuts 47, arranged in bifurcated brackets 48, rigidly secured to the wall-sections 35 37, (see Fig. 6,):

the nuts 47 being held against rotation with the screw by dogs 49, so that when desired the dogs 49 may be released and the wall-sections 35 37 adjusted on the screw 46 with relation to each other; but when the screw 46 is turned in the nuts 47 thewall-sections 35 37 will be moved in unison relatively to'their The brackets 48 are also formed with collars 50, through which passes the rod 39, but which slide freely on said rod for guiding and steadying themovable wall-sections.

Extending across the outer ends of the wallsections 34 to 37 is 'a rod 51,similar to the rod 39, which passes through collars 52 53, adapted to be secured rigidly to the rod 51 by set-screws 54 55 or other suitable means, and which collars have both swivel and sliding connection with the. wall-sections 34 36", the form of such swivel and sliding connection being best shown in Figs. 7 to 9, in-' elusive, and which, it will be seen, consistsof a pivot 56, passing downwardly through a slot 57 in 'a flange 58, secured to or formed on the back of the wall-section, one of these flanges 58 being on each of the wall-sections 34 36*, and the lower end of the pivot 56-bel0w the flange 58 is provided with a retainingmeans,

such as a nut 59, to prevent it from slipping out of the slot while permitting it to run longitudinally of the slot as the wall-sections 34 36 are turned on their hinges 38 for varying the angle of the corner to be molded. Then the desired angle ,or adjustment of the hinged wall-sections is attained, they may be locked to the rod 51 by the set-screws 54 55. The pivot 56 may be given connection-or attachment to the collars 52 53 in any suitable way. They are shown as being formed on downward extensions 60 61, respectively, and through these extensions loosely passes a screw 62, similar to the screw 46 and arranged parallel therewith across the ends of the hinged wall-sections' The hinged wall-sections 35 and 37 have screw-threaded connection with the screw 62, and the screw 62 is connected to the screw 46 by means of sprockets 63 64 on the screws, respectively, and connecting chain-belt 65, an operatinghandle 66 being on the screw 62, so that when the operating-handle is'turned both screws will be rotated, and as'a consequence both ends of each of the movable mold-walls 35 35 and 37 37 will bemovcd'back and forth in unison. This screw-threadedconnection between the wall-sections 35 and 37 is produced by nuts 67 68, arranged in slide members 69 70, respectively, and held therein against rotation by dogs or pawls 71, except ing when it is desired to change the angle of the mold-Wall, when the dog 71 would be disengaged and the nut 68 rotated until the desired adjustment be attained. The slide members 69 7 O slide loosely upon the rod 51, the rod being passed through them, and their lower ends are provided with pivots 72, (see Figs. 4, S, and 9,) passing downwardly through slots 73 74 in plates or flanges 75 75, respectively, secured to the hinged wall-sections 35 37*, so that as these sections are turned on their hinges for the purpose of changing the angularity their outer ends may be free to move transversely of the screw 62, while they at the same time maintain their attachment to the slide members 69 70, the lower ends of the pivots 72 being provided with nuts 77 or other suitable means for holding them in place.

The rods 39 51 are connectedtogether at both ends by cross-bars 78 79, so as to constitute a rectangular rigid frame, maintaining the parallelism of the screws 46 62, which, as before explained with reference to Fig. 1, are fixed against longitudinal movement in any suitable way, as by pins 80 81, secured in the members 42, 52, and 60 and engaging in rooves 82 in the screws, one of these grooves eing shown with reference to the screws 62 in Fig. 7 and the other in the screw 39, being the same and not necessary to illustrate.

For the purpose of bracing the wall-sections 34 34 they are provided on their outer side with a connecting rod or brace 83, se-

cured by a bracket 84 to the section 34 and by a bolt 85 and plate 86 to the section 34, the plate 86 having a longitudinal slot 87, in which the bolt 35mins when section 34 is turned on its hinge in changing theangularity.

The wall-sections 37 37 may be braced at or near their lower edges by braces 88 89, which slide on the rods 39 51 in unison with the wall-sections when, the screws are rotated, thus keeping in close touch with the wall-sections 37 37, to which they may be secured. at their lower ends by any suitable means. The brace 88 for the hinged section 37 however, has sliding connection at its lower end with such sections 37, consisting of any suitable means, such as a late 90, having a slot 91, in which runs a boft or stud 92 on the lower end of brace 33, so that as the angularity of the hinged section 37 is altered and its end moves transversely of the screw 62 the brace may be released from the section 37 for the time being. This brace 88 is connected to the screw 62 by means of a nut 93, like the nuts 67 68 which is held again..t rotation by means of-a dog 94, similarin all respects to the dog 71, Fig. 9, so that when the (10.2; is released the brace may be properly adjusted to suit the changed position of the section 37.

In the form of the invention shown in Figs. 11 to 16, inclusive, the mold-walls 95 96 97 93 are curved from end to end, making the machine suitable for molding silos or curved walls. The walls 96 98 are movable with relation to their companion walls and are moved as desired by means of parallel screws 99 100, extending across the upper edges thereof and connected together at one end by a sprocket-chain or suitable belt 101 running around sprocket-wheels 102 103 on the screws 99 100, respectively, so that when one screw is turned by means of a handle 104 the other will be rotated in the same direction. The mold-walls are each provided with a pair of brackets 105 106 107 108, respectively. The brackets 105 are provided with pins 109, which engage in grooves 110 in the screws 99 100 for holding the screws against longitudinal movement with relation to these two brackets, and the brackets 106 and 108 are provided with nuts 111 112, constructed and arranged as shown in Figs. 15 and 16 for giving the screws operatively connection with the walls 96 98, Figs. 15 and 16, which show the construction for all these nuts, will be readily understood from the description with reference to Figs. 8 and 9, the nuts 111 112 being held against rotation on the screws 99 100 by dogs or pawls 113 for the purpose defunction to the rods 22 23, while collars 115 have set-screws 117, whereby they are I claim as new therein, and desire to secureby Letters Patent, is v 1.
